Impact detection circuit and protection plate

The invention is suitable for the technical field of protection plates, and provides an impact detection circuit and a protection plate. The impact detection circuit comprises an impact detection unit and a logic control unit, the impact detection unit is arranged on the protection plate, and the impact detection unit is electrically connected with the logic control unit. When the impact energy borne by the protection plate is larger than or equal to the preset impact energy, the protection plate can deform within the local impact range, and the deformation quantity reaches the preset deformation quantity. The impact detection unit is changed from the first state to the second state, and the logic control unit outputs a logic alarm signal when the impact detection unit is in the second state to warn a system monitoring center so as to timely process the protection plate. According to the impact detection circuit provided by the embodiment of the invention, the impact condition of the protection plate is monit
